Chinese and foreigners' car habits are different, the frequency of maintenance of cars is also different, many Chinese car owners are too fond of cars, 5,000 km to 8,000 km to change the oil once. Foreign car owners change the oil frequently, 20,000 to 30,000 kilometers only once, how big is the gap between the four and the two?
The oil is equivalent to the blood of the car, and the oil will be injected into the engine when starting the vehicle, forming an oil film on the surface of the parts, providing anti-corrosion, anti-rust, corrosion and anti-wear effects.
Chinese car owners change the oil more frequently, mainly because they love cars more, and Chinese owners are worried that not changing the oil for a long time will lead to increased engine wear. Foreign car owners change the frequency of oil is relatively long mainly to save money, they think that high-quality oil with 20,000 kilometers is not a problem at all, there is no need to change so cheap.
Normal oil change interval:
There are mainly fully synthetic oils and semi-synthetic oils on the mainland market, and fully synthetic oils are artificially manufactured oils, and some natural substances are added to the oil for chemical decomposition. The biggest difference between fully synthetic oil and semi-synthetic oil is that the temperature of fully synthetic oil is wider and the service life is longer.
Chinese used to change the oil according to the mileage, if you use a fully synthetic oil, you can do 10,000 kilometers to change the oil, if you use semi-synthetic oil, 8,000 kilometers to change the oil.
Foreigners are accustomed to changing the oil according to the time, using the full synthetic oil once a year, and using semi-synthetic oil 8 once a month. According to the normal car cycle, about 20,000 kilometers a year are driven, so foreign car owners only change the oil once for 20,000 kilometers.
The harm of long-term oil change:
First, increase engine wear.
The engine is a machine where various parts are combined together, and not changing the oil for a long time will lead to oil deterioration and deposition, which cannot protect the engine, and the wear of each part is very serious when running.
Second, it cannot be cooled effectively.
In addition to being a heat sink or a coolant, the heat absorption performance and thermal conductivity are higher than water, the oil can play a cooling and cooling role during the engine operation, and the oil is not changed for a long time, resulting in oil deterioration and lack, the engine cannot dissipate heat, and the performance will become worse.
Third, corrosion of engine parts.
Not changing the oil for a long time will cause the oil to deteriorate, and the spoiled oil will produce many impurities and sediments. The long-term presence of magazines in the engine will lead to increased engine wear, and some impurities will also corrode the machine parts in the engine.
Fourth, it cannot be effectively sealed.
Engine oil is a viscous liquid that seals the engine. Not changing the oil for a long time will lead to oil deterioration, diluted oil can not effectively plug the gap between the cylinder block and the piston, which will lead to gas leakage in the engine and affect the engine power.
Editor's Comments:
Foreign car owners have not changed the oil for a long time, and after three years, the engine has experienced serious wear and tear, and the performance is getting worse and worse. I hope that Chinese car owners develop good car habits, if you use fully synthetic oil must be done 10,000 kilometers and replace once every six months, a long time without changing the oil will bring many negative effects, the performance of the car is getting worse and worse, the engine will also have problems, how often do we change the oil?
